Auto Replant Tree

Automatically replants saplings when you break a log block. Works on the server — no client mod needed.

Features

• All vanilla trees — Oak, Spruce, Birch, Jungle, Acacia, Dark Oak, Mangrove, Cherry, Pale Oak
• Nether trees — Crimson and Warped stems replant their respective fungi on nylium
• 2x2 support — Dark Oak and Jungle trees replanted as a 2x2 grid
• Sneak to cancel — Hold sneak while breaking to skip replanting
• No-sapling mode — Set requireSapling: false to plant without consuming saplings
• Stripped & wood variants — Recognizes all log, stripped log, wood, and hyphae variants
• Full inventory search — Finds saplings anywhere including offhand
• Per-tree config — Enable/disable specific trees via config/autoreplant.json

Supported Versions

How It Works

1. Break a log block
2. Holding sneak? (if sneakToDisable: true) → Skip
3. Matching sapling found in inventory? (skipped if requireSapling: false)
4. Ground valid? (dirt, grass, nylium, etc.)
5. Sapling planted, one consumed from inventory (none consumed if requireSapling: false)

Configuration

Config file at config/autoreplant.json:

{ "sneakToDisable": true, "requireSapling": true, "trees": { "oak": true, "spruce": true, "birch": true, "jungle": true, "acacia": true, "dark_oak": true, "mangrove": true, "cherry": true, "pale_oak": true, "crimson": true, "warped": true } }

• Set any tree to false to disable its auto-replant
• sneakToDisable: false → always replant regardless of crouching
• requireSapling: false → plant without consuming saplings

Installation

Drop the jar into your server's mods/ folder. Works server-side only — no client installation needed.
